The Monitor air pad bin aerator is an aeration
device used to promote the flow of dry bulk powders from
a storage vessel.

Principle of Operation

The Air Pad operates by continuously introducing air
into the body of the dry powder. When a powder is first conveyed
into a storage vessel it is actually a highly aerated mixture
of air and particulate. In this state the mixture flows quite
readily. However, as the powder settles the solid particulate
and air separate resulting in a decrease in volume and an
increase in bulk density. In this deaerated state powders
can behave more like a single large solid structure rather
than a fluid-like mixture. By replacing the naturally lost
air, the air to particulate mixture ratio is held thus maintaining
the fluid like characteristic of the aerated powder.

Applications

For best results in promoting the flow of dry bulk powders,
multiple rows of air pad bin aerators should be used. The
number of rows and quantity of air pads in each row will
differ by application. Monitor application engineers are
ready to provide you with the best recommendation for your
specific material flow problem.

Generally, four rows of air
pad bin aerators on 12 inch (305mm) or 15 inch (381 mm)
centers is recommended. While the effective radius of each
air pad
is approximately 10 inches (254 mm), the air pads should
be spaced so that the entire troublesome area is within
the sphere of influence of the air pads.

Typical Applications include,
but are not limited to:

Cement

Bentonite

Gypsum

Soda
Ash

Lime

Flour

Carbon
Black

Fly
Ash

Resins

Features

Accessories

An external mounting kit is available. This
kit can completely eliminate the need to enter the bin to
install or service air pad bin aerators. Using a 2-5/8 X
6-5/8 inch (66.5 x 162 mm) cutout hole in the bin wall,
the mounting kit can be completely installed and serviced
from
outside the bin. Our air pad and external mounting kit can
easily install in existing cutouts of other brands.

The external
mounting kit includes gaskets, clamp bracket, rectangular
mounting bracket and necessary hardware for mounting with
your air pad bin aerator and its mounting hardware. An
external mounting kit for high temperature applications is
also available.

QuantiMassTM
Mass Flow Measurement Systems

The QuantiMass in-line mass flow sensor measures the flow of quantities in pneumatic conveying & free-falling processes. The sensor is based on the latest Microwave Doppler Effect technology and provides fast, in-line / on-line measuring without the use of weight scales.

The sturdy, non-intrusive design of the sensor minimizes maintenance. In addition, the compact size of the sensor makes for easy installation into existing processes. Suitable for powders, dust, pellets, and granular up to 0.75 inch (2cm).

A practical application for the QuantiMass would be to monitor material flow rates to verify blending mixture ratios.

Principle of Operation:
The QuantiMass Mass Flow Measurement Sensor / Meter is designed with the latest microwave technology and is used to continuously quantify the flow of powders & solids being conveyed in metallic pipes. The QuantiMass is based on technology that has been developed and proven by Muetec Intruments over several years. The measurement process of the sensor is centered on the Doppler effect. The mass flow-rate is determined by evaluating the frequency and amplitude changes during the measurement process. Particles at rest, such as deposits, do not influence the measurement. All powders, dust, pellets and granules can be measured reproducibly, up to the size of 0.75 inch (2cm). The QuantiMass sensor is suitable for continuous in-line / on-line measurements in pneumatic conveying or in free-fall pipelines.
